The periodic table of elements is a table full of elements found in the earth. It has three categories metal, nonmetal, and metaloids. it is so interesting to me. Also I learned a lot about the periodic table and its elements. I learned that they all have abbreviations and when you combined elements together you get combines but that is a different story. I also learned that metaloids are used in a lot of electronics, and all the elements make up something we use today. I am glad the periodic table sorts and has all the elements on it or else it would be confusing.
